No cool a/c repair call for the downstairs. Checked and found a/c system ductwork undersized and not run properly for the house. Found heatpump capacitor weak, poor filter system due to no filter rack, found system have not drain pan, and no overflow protection in the basement. Suggest the customer replaces the capacitor and install compressor hard start kit to improve startup and reduce the load on the unit. Installed hard start kit.
